A custom shield for using a SIM800L-based GPRS transceiver to connect to the internet over GSM. This is designed to be driven by a SparkFun SAMD21 Mini board, and includes a 128x64 OLED display and an NRF24L01+ 2.4GHz RF module. It's powered by a lithium-ion battery (18650), and has a microSD port to archive data.

Template (PCB and interface symbol) to copy for any kind of HAT designs for Raspberry Pi B+. The PCB contains 6 layers with layer display at the lower edge. The assignment of layers is:
- top: signal, polygon connected to GND
- bottom: signal, polygon connected to GND
- layer 1: inner, signal
- layer 2: inner, polygon VCC
- layer 3: inner, polygon GND
- layer 4: inner, signal

This is not in any way my design or idea. It's based on the work of Daniel Perez over at https://generatorlabs.wixsite.com/spectrum.
I just converted the pdfs of the schematics and made some small improvements for easier connectivity, to allow anyone who want to build it theirself.
I thank him so much for sharing this awesome project along with the arduino code. Please check out his 3 part video...
# ESP 32 input output board/ shield #
8 opto-isolated inputs
8 10 amp relay outputs
Serial, 1 Wire comunication ports.
Just plug in a ESP32test module and programm it.
Used it with Jeedom and the Jeeduino plugin.
This shield is designed for easy powering and using four GPIOs of ESP-01/01S module. It is powered by 5 volts DC and has four 3-pin screw terminals for connecting some periphery like 2812 LEDs, relay modules, etc.
Shield for Wemos D1 Mini. It provides two 3.3V GPIO and two 5V GPIO each with supply voltage, and ground terminals.
The two 3.3V GPIO have provisions for optional pullup resistors. These can be used with sensors or 1-wire devices requiring pullup.
Two additional GPIO are for 5V devices with level shifters to provide 5V Input or Output that is compatible with 3.3V GPIO on the Wemos.
